Queensland Fisheries confirmed it has been patrolling the net free zone since Tuesday.

After reports of the dead turtles the patrol has focused on the waters off Seaforth.

A Fisheries Queensland spokesperson said the initial patrols were part of routine patrols in the region. "After receiving a report about a dead turtle, the overnight patrol on Wednesday was tasked to focus on the area around Seaforth," the spokesperson said.

"Fisheries officers have not detected any dead turtles."

A Department of Environment and Science spokesperson said it was unaware of an increase in turtle deaths.

"DES received a report from the member of the public of two dead turtles at Rabbit Island on March 13," the spokesperson said.
